Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525870, here are decompositions:

11 + 33525859 = 33525870
19 + 33525851 = 33525870
67 + 33525803 = 33525870
97 + 33525773 = 33525870
113 + 33525757 = 33525870
139 + 33525731 = 33525870
163 + 33525707 = 33525870
179 + 33525691 = 33525870

Showing the first eight; more decompositions exist.
